Image Credit: Laser Quantum Ltd A Brief Introduction to SEM and TEM It is important to discuss the main working principles of EM before outlining the principles of time-resolved electron microscopy.

Detection of either kind of electron allows for reconstruction of the size of the imaged object as well as visualization of any more complex structural features. Cryo-electron microscopy (cryo-EM) ...

Cryogenic-electron microscopy (cryo-EM) has rapidly become one of the most important experimental methods in structural biology and nanoscience. In this article, AZoNano discusses the working ...

Electron Source Much like the traditional scanning electron microscope (SEM), the field emission scanning electron microscope uses electrons to illuminate a sample, instead of visible light as is used ...

Radiation damage remains the principal limitation in achieving higher resolution in cryo-electron microscopy (cryo-EM), ...

Since they came into use in 1938, electron microscopes have played a pivotal role in a host of scientific advances, including the discovery of new proteins and therapeutics and contributions made to ...

A team from Ireland has done just that and published their results using machine learning to enhance STEM — scanning transmission electron microscopy. The result is important because it targets ...

Critical Dimension Scanning Electron Microscopy (CD-SEM) is a specialized technique used for high-resolution imaging and precise measurement of nanoscale structures in semiconductor manufacturing and ...

Researchers at Forschungszentrum Jülich and Heinrich Heine University Düsseldorf led by Prof. Dr. Carsten Sachse are using cryo-electron microscopy, or cryo-EM for short, to make biomolecules ...
